Prokaryotes are the single-celled organisms of domain bacteria and archaea which lacks a nucleus and membrane-bound organelle while eukaryotic cells are the organisms which contains a well defined nucleus and other membrane bound organelles.
The fundamental difference between prokaryotes and eukaryotes is the presence of DNA(genetic material) in a membrane-bound organelle called nucleus which is absent in prokaryotes where genetic material is stored in an area called nucleoid which is not surrounded by the nuclear membrane.
The compartmentalisation of DNA confers stability to the cell as genetic material is protected from the external bodies and injuries.
C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.
Explanation;
Aldosterone hormone is produced by the adrenal gland and mainly carries out its functions in the kidney.Through the aldosterone hormone the body is able to retain more water for the kidney is able to hold more sodium.
When the plasma sodium levels decrease and the plasma potassium levels increase the production of aldosterone hormone is stimulated for sodium is needed in the .body to maintain the high water levels in the body.
